Mick Foley got it right in his book that wrestling should be like the circus. You have acrobats, liontamers, jugglers, etc. and try to have at least one act that everyone will like.
That's why Nitro was fire in 1996 and 1997. You had a high-flying cruiser match, a technical masterpiece, a brawl, a garbage match, and also hot angles in all parts of the card with a lot of good talkers
WWE has a boring house style and all the matches feel the same in terms of layout, and they haven't had a hot angle on the main shows in literal years. Daniel Bryan YESing and trying to get to the main event was the last time they even got remotely close to getting any mainstream attention after YES caught on briefly at a handful of sporting events. Watch that cage match with Bray Wyatt in nowheresville Connecticut and that crowd was MOLTEN when Bryan turned against Bray in a way I hadn't seen a crowd since like 2001.
They need to look at 1996/97 Nitro as the blueprint for how to book a wrestling show as broadly as possible. Then, they need to basically redo classic angles from the '80s and '90s that most of the audience has forgot existed, because they can redo them for modern audiences with new characters
